Concatenation is to assign the low 3 bits signal and the input signal together. This article takes four-bit serial-to-parallel conversion as an example. Module ser_to_par_converter(ser_in,par_out,clk) Serial to parallel conversion uses shift registers. A controller, a counter unit, a PIPO unit and a SIPO unit. Here is the code for converting serial data received through rs232 cable to parallel data.
